Help to QUICKLY Kill Algae

Hey everybody. I went out and checked my pool for the first time in a couple days and I've got an algae bloom going on in several areas. I want to completely get rid of it but also want to use the pool this weekend and need the Cl levels to be swimmable for us and the kids by tomorrow. I'm off today so I can work on it as needed. If I SLAM it, the levels will likely be too high to swim tomorrow. What would you recommend doing?

FC - 6.5
CC - 0
pH - 7.5
TA - 70
CH - 80
CYA - 60
Salt - 3140

As you can see, my FC levels are reasonably high. That's because I noticed they were low about 3 days ago and cranked the SWG up to 100%. Looking back, I'm guessing I already had an established algae bloom at that point and all I did was slow it down.

Algea will die at its own pace. Pool is safe to swim in up to SLAM FC levels. Raise the FC with bleach and let the kids swim. It is as safe as any pond or public pool.

Or wait and let kids swim and raise FC to SLAM after the weekend. Some algea in the pool does not make it unsafe to swim.

Ok, I'm going to SLAM then. Part of it is I'm going away next weekend for 10 days and want the pool to be perfect and stable before I leave so I don't come home to a mess. This weekend is my true opportunity to get it perfect. Thanks.

SLAM started. At what point can I put my robot (Pentair Kreepy Krawler) back in the pool. I know it says not to do it when super-chlorinating but it doesn't give an actual FC level.

Mixed responses on that. Some won't use a robot during SLAM. I would not suggest leaving them in the pool except for their cleaning cycle. Then clean the filters and spray it down with fresh water.

If SLAM level FC does not bother my skin, I do not see how it will bother hard plastic -----

I guess it depends on the robot. I only have a Polaris so I take that out. I don't want it stirring up the bottom after I brush but before I vacuum. If yours is a vacuum that is a different story.
